We´ve a problem with pssm.
When sun_angle.tilt is low, the shadows are disappearing at certain camera angles.


sun_angle.tilt is low, shadows are visible:


sun_angle.tilt is low, camera angle has changed, shadows are not visible:


sun_angle.tilt is high, shadows are visible:


sun_angle.tilt is high, camera angle has changed, shadows are visible:



If I comment #define DEBUG_PSSM in the shadowmaps are shown, but they are not rendered. What could be the reason for this behavior?

no science involved
